DRIVE
May 6, 2026
A negative electrode sheet, a fabricating method, and a battery are provided. The negative electrode sheet includes: a current collector; a first active layer is provided on a surface of at least one side of the current collector, and a second active layer is provided on a surface of one side of the first active layer away from the current collector, the first active layer is different from the second active layer, the first active layer includes a first active material including a first graphite, and the second active layer includes a second active material including a second graphite; a ratio of capacity per unit mass of the first active material to specific surface area of the first active material is a first capacity ratio, and a ratio of capacity per unit mass of the second active material to specific surface area of the second active material is a second capacity ratio, a ratio of the second capacity ratio to the first capacity ratio being greater than 1. In the negative electrode sheet of the present application, different active layers are coated on the current collector, thereby increasing the cycle life of the negative electrode material, reducing the expansion rate, increasing the capacity and volumetric energy density of the battery, and prolonging the cycle life.
